10. The system of claim 4 , wherein the at least one segment of interest further comprises at least one demographic category, the at least one demographic category being at least one of: sex, age, income, race, marital status, familial status, home ownership status, employment status, language, or geographic location.

11. The system of claim 4 , wherein the user behavior application further comprises logic that calculates a confidence score associated with the assignment of the unauthenticated user to the segment assignment based at least upon the highest percentage of the plurality of authenticated users who are known to have exhibited the at least one behavior of interest.

12. The system of claim 11 , wherein the user behavior application further causes the at least one computing device to at least: observe a second user behavior associated with the unauthenticated user; determine whether the second user behavior corresponds to another historical behavior associated with the at least one segment of interest; assign the unauthenticated user to a segment assignment corresponding to the another historical behavior within the at least one segment of interest; and update the confidence score associated with the assignment of the unauthenticated user to the segment assignment based at least upon the percentage associated with the segment assignment and the second user behavior.

13. A method, comprising: identifying, in at least one computing device, a plurality of authenticated users for which at least one segment assignment in at least one segment of interest is known based upon a respective user account of individual ones of the plurality of authenticated users; identifying, in the at least one computing device, at least one historical user behavior associated with at least a subset of the authenticated users; calculating, in the at least one computing device, for the at least one historical user behavior, a percentage of the plurality of authenticated users in at least one possible segment assignment associated with the at least one of segment of interest that exhibit the at least one historical user behavior; storing, in the at least one computing device, the percentage in a data store accessible to the at least one computing device; establishing, in the at least one computing device, a session associated with an unauthenticated user for which the at least one segment assignment in at least one segment of interest is unknown; observing, in the at least one computing device, a behavior associated with the unauthenticated user; identifying, in the at least one computing device, the at least one historical behavior corresponding to the behavior associated with the unauthenticated user; identifying, in the at least one computing device, a segment of interest associated with the at least one historical behavior; associating, in the at least one computing device, the unauthenticated user with a first segment assignment in the segment of interest; and targeting, in the at least one computing device, the unauthenticated user with content that is relevant to the first segment assignment.
